ROD-ROLLING MILL.

To all whom 'it mayconcern;

Be it knownthat I, HUGH L. THoMPsoN, a citizen of the United States, residing at VVaterbury, in the county'fof New Haven and State of Connecticut, .haveinvented a new and useful Rod-Rolling Mill, of which the following is a specifications .My invention relatesto improvements in rod-rollingmills the rollingoperation has been completed,

said various means arranged relatively so as a to occupy a minimum area of mill floor space.

Referring to the drawings :Figure 1 is a side elevatlon of mydevice showing the rolls in section. 2 is a similar view, on an en- 'larged scale, or the rolls, drum and coiler.

Fig. 3 is a fragmentary plan view of same.

Similar. numerals refer to similar parts throughout the several ,views.

The device illustrated in the drawings com prises a set or train of three-high rolls. These rolls 4, 5 and 6 are positioned one above the other; their axes being in a vertical plane. To the "rear of the rolls, and in close proximity thereto, located a stationary structure 7. This structuresup orts the table 8 provided with T.-bolts. 9,qa apted to slide in the T-channelS 10 of structure 7, so that table 8 is adapted to havea horizontal movement parallel with the axes of the rolls. Ta ble 8 is provided withT channels 1 1 arranged transversely to channels 10 in which are adaptedto slide similar T-bolts secured to the drum member 12 so that said drum member 12 is "capable of a horizontal movement to and away from the rolls, and also by moving the table, 8, the :drum l2is capable of a horizontal movement parallel with the rolls.

Mammalian The stationary structure 7 also supports the elements 18, 14 and 15 ofthe coiler. These elementsare so disposed as to cause the rod 16 to be coiled-beneathsaidelements into the pit 17. The trough, tube, or channel 18 is located on the other side of the rolls, is in- I I Specification ofLetters Patent. fApplication filed July 23, 1906. Serial No. 327,299.

clined upwardly from the rolls, and is adapted. to receive the rod as it passes from one set of rolls and to return it to the other set of rolls.

The operation of my device is as follows The rod, in the form of a coil, is placed upon the drum 12, in the position indicated by dotted lines in Fig. 2. The end of the rod is straightened from the coil to the length of four or five feet. The drum 12 is then moved into the position shown in solid lines in Fig. 2, to facilitate the operator in introducing the end of the rod between rolls 4 and 5, in

the direction of the arrow. As the rod passes through the rolls 4 and 5, it is introduced into the trough or channel 18, which inclines upwardly from approximately the horizontal plane passing between rolls 4 and 5. The rod is forced upwardly in the trough or channel 18, until it entirely passes from between rolls 4 and 5. It is now in a most convenient position for the operator to intro- ,7

duce the rear end of the rod 16 back between the rolls 5 and 6 for further reduction of the same. It will be noted that gravity assists the operator in introducing the rear end of the rod between the under pair of rolls and it also assists in feeding the rod thereto. As

the rod passes from between rolls 5 and 6 it passes between the elements 13, 14 and 15 of the inverted coiler forming said rod into a coil beneath the coiler elements and beneath the drum supporting table into the pit 17.

nection with girders 20, 21 and 22 so that the same will swing to permit the movement of the mouth or end of trough or channel 18,

which is near the rolls, in a substantially horizontal direction, so that the same may be brought into substantial alinement with the grooves of the rolls through which the rod is traveling. The horizontal movement of the drum 12 parallel with the axes of the rolls is for the same purpose.

What I claim is 1. The combination of cooperating rolls and a combined coil supporting drum and inverted coiler structure in close proximity to the rolls.

2. In a rod rolling mill, the combination of cooperating rolls having back and forth passes, an inverted coiler in close proximity thereto, and a coil supporting drum superimposing and supported by the coiler structure.

3. In a rod rolling mill, the combination of upper roll and having an overhead suspended hinged support so that it may swing into approximate alinement with the several passes of the rolls.

5. In a rod rolling mill, the combination of cooperating three hlgh rolls having back and forth passes, a channel structure inclined downwardly and toward the rolls for substantially its entire length for guiding and supporting the rods, having its end toward the rolls substantially removed therefrom, as and for the purpose specified.

6. In a rod rolling mill, the combination of cooperating rolls having back and forth passes, an inclined channel structure extending upwardly from approximately the height of the upper rolland having part of its extension toward the rolls provided with overhead suspended hinged sup orts to permit of substantially 'horizonta movement for approximate alinement with ,the several passes.
